Global Silicon Nitride, Silicon Nitride Overview, Silicon Nitride Applications, Silicon Nitride Suppliers, Silicon Nitride Price market trend 2025-2026 Overview of Silicon Nitride Si3N4 by Newsncnblue

Commodity prices are on track for their biggest rally in more than a century, while fixed-income assets have seen their longest run of outflows as the war in Ukraine adds to inflationary pressures in the global economy emerging from the coronavirus lockdown, according to Bank of America.

"Commodity prices this year are on track to record their biggest gains since 1915." the bank said in its weekly briefing. They cite many factors, such as pandemics, lockdown, civil strife, wars, excessive monetary and fiscal stimulus, and supply chain disruptions, that have led to "historically" high inflation.  

By the same token, it said government bonds were heading for their worst year since 1949, and "negative-yielding bonds will quietly disappear" from the market as central banks embark on a monetary tightening cycle and raise interest rates to tame soaring inflation.  

The prices of many commodities like the Silicon Nitride, Silicon Nitride Overview, Silicon Nitride Applications, Silicon Nitride Suppliers, Silicon Nitride Price are expected to increase in the future.

Overview of Silicon Nitride Si3N4

Silicon nitride is a compound of silicon and nitrogen. Si3N4 is the most thermodynamically stable in silicon nitride. It is a white, high melting solid, relatively chemically inert, attacked by dilute HF and hot H2SO4. It works very hard (MoHS is 8.5) and has high thermal stability.


How is silicon nitride Si3N4 powder produced?

Hexagonal β-Si3N4 can be directly carried out with silicon nitride and nitrogen can be carried out at 100-1400 °C.

SiCL4(L)+6NH3(g)→Si(NH)2(S)+4NH4Cl(S) at 0℃

3 Si(NH)2(S)→Si3N4(S)+N2(g)+3H2(g) at 1000℃

Or thermal reduction reaction with carbon under nitrogen atmosphere at 1400-1450 ℃ under nitrogen atmosphere:


However, if the silicon raw material used is of high purity, it will cause silicon nitride to contain impurities such as silicate and iron. The silicon nitride synthesized by the decomposition of diamine is amorphous and needs to be further annealed at 1400-1500 ℃ in nitrogen to be converted into crystalline powder. Only the decomposition of diamine is important. Silicon nitride is commercially produced by the nitridation process. Carbothermal reduction reaction is the simplest method for producing silicon nitride, and it is also the most economical and efficient method for manufacturing silicon powder in industry.

Electronic grade silicon nitride films using chemical vapor deposition or plasma enhanced chemical vapor deposition techniques

3 SiH4 (G) + 4 NH3 (g) → Si3N4 (S) + 12 H2 (g)

3 SiCL4 (G) + 4 NH3 (g) → Si3N4 (S) + 12 HCl (g)

3 SiCL2H2 (G) + 4 NH3 (g) → Si3N4 (S) + 6 HCl (g) + 6 H2 (g)

Application of silicon nitride Si3N4 powder

1) Manufacturing structural devices: metallurgy, machinery, aviation, aerospace, etc.

2) Surface treatment of metals and other materials: such as molds, tools, turbine blades.

3) Composite materials: such as metal, ceramic and graphite composite materials, rubber, plastics.

4) Colorless, transparent, self-lubricating and wear-resistant nanoparticle film for advanced surface protection such as mobile phones and automobiles.

5) Ball bearings.

6) Ball valve and parts.

7) Corrosion resistant turbine.

Chemical Composition of Silicon Nitride Si3N4 Powder


In a recent speech in Davos, Switzerland, Ukrainian President Volodymyr Zelensky criticized, "My question is: Is there unity in the West? "I don't see it," Zelensky lamented during a video conference from the Davos Economic Forum in Switzerland. "Ukraine needs the support of a united Europe."

"Is there talk of solidarity with Sweden and Finland joining NATO? No." "So is the West united?" Zelensky said at this Ukraine-hosted breakfast in Davos. No." "Our strength is unity within the country," Zelensky said. "Now it depends on the Unity of the West to stand strong and firm behind Ukraine against Russia.

According to Zelensky, "When we are all really united, we will have an advantage over Russia."  

Ukrainian President Volodymyr Zelensky says he once again appreciates U.S. President Joe Biden's offer of $40 billion in new financial aid to Ukraine.  

"We need the support of a united Europe," Zelensky stressed. Zelensky criticized the position of Hungarian Prime Minister Viktor Orban, who is reluctant to impose an embargo on Russian oil at this stage. "Hungary has a problem!" Zelensky criticized.

The supply and prices of many other Silicon Nitride, Silicon Nitride Overview, Silicon Nitride Applications, Silicon Nitride Suppliers, Silicon Nitride Price are expected to continue to be influenced by changing international situations.
